SPECIFICATION forming part of Letters Patent No. 341,549, dated May 11, 1886.

Application filed February 1'7, 1886.

. E. The two cylinders are closed at their ad To all whom it may concern.-

Be it known that I, WILLIAM BROWN, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new anduse- 5 ful Improvement in Steam-Engines, of which the following is a specification.

\Vhatare known as tandem engines, and p which are commonly compounded, have the two cylinders arranged in line, one above the other, the lower cylinder commonly being the larger and low-pressure cylinder. In such engines the upper cylinder is supported from the lower cylinder; and my invention consists in a novel construction of this support, which I enables a portion thereof to be readily re-I moved without disturbing the other cylinder and pipe-connections; and in order that access may be readily had to the upper and lower cylinder-heads for removing them, and to the lower piston in case it be desired to remove it from its rod or to have access to its packing, I preferably make this support in the form of a circular structure, which is composed of upper and lower rings, or circular flanges bored to fit outside the upper and lower cylinder heads, and struts or standards extending between and connecting the rings or flanges. Such circular support is divided vertically, it being composed of two or more arc-shaped sections which are bolted together, and whenever desired one portion of the support may be removed without removing the other portion or portions thereof, and without in any way disturbing the connection of such other portion or portions with the two cylinders.

In the accompanying drawings, Figure l is a vertical section of an engine embodying my invention. Fig. 2 is a side elevation,looking from the right hand of Fig. 1. Fig. 3 is a side elevation, upon a larger scale, of the uppercylinder support, which constitutes my invention; and Fig. 4 is a plan of such support upon the same scale as Fig. 3. v

Similar letters of reference designate corresponding parts in all the figures.

But little description of the ordinary parts of the engine is required to give a clear un' derstanding of my invention.

A B designate the upper and lower cylinders, which are arranged in line, and which contain pistons OD, secured to a common rod,

jacent ends by heads A B, provided with suit able stufiing'boxes, a b. The upper cylinder is supported in proper position by a support, 5 F, which embodies my invention, and which is itself superposed on the lower cylinder, B.

It is often desirable to remove the cylinderhead B, in order that the piston D maybe lifted above the cylinder B, and, if desired, removed therefrom; and the support F is of a novel construct-ion which permits of this being done without disturbing the upper cylinder or any of the pipe-connections or valvegear connected therewith. This support is 6 best shown in Figs. 3 and 4, but is also illus trated in Figs. 1 and 2. It consists, essentially, of upper and lower rings or circular flanges, ff, and struts or standards f f extending between and connecting the rings or flanges ff. The upper and lowersurfaces of the rings or flangcsff are faced off, so as to fit flanges on the cylinders A B, and they are bored out, so as to fit the edges of the cylinder-heads A B. The circular support F is 5 secured upon the upper flange of the cylinder B by bolts 0, and the upper cylinder, A, is to be secured upon the upper ring or flange, f, of the support by means of bolts, (nothere shown,) and which are to be inserted through holes f*. (Shown in Fig. 4.)

The circular support F is composed of sections, or, in other words, is divided vertically, so that a portion of it may be removed without disturbing the remaining portion or portions. As here'reprcsented, it is divided at the points 9, (see Fig. 4,) and is composed of two semicircular sections, secured together by bolts 9. The line of division, 9, passes through the struts or standards f, and these struts or 0 standards are ribbed upon the outside, as shown at f, to give them the necessary strength.

The struts or standards f f are each provided with lugs or ears 0, for the reception of the holding-down bolts 0, and the struts or 5 standards f are provided with laterally-extending lugs or cars for the reception of the bolts 9, by which the two sections are secured together.

Between the struts or standards f f the [00 support is left open between the upper and lower rings, f f, in order that ready access may be had to the stuffing-boxes a b of the upper and lower cylinders.

\Vhenever it be desired to remove the cylinder-heads A B, either or both of them, in order that access may be had to the pistons O D, or if it be desired to remove the lower piston, D, also, all that is necessary is to loosen the bolts which confine one section or part of the support F and leave the other section or part of said support firmly bolted to the two cylinders. In order to admit of one half of the support being removed, it is only necessary to take out the bolts and the bolts c which pertain to that half, and to unbolt it from the two cylinders, and it may then be removed laterally from its place, leaving the upper cylinder firmly supported by the other half or section of the support F.

Inasmuch as the support is circular and bored out to truly fit the exteriorof the heads A B, it may be cheaply produced by lathework, and furnishes a means of properly placing the cylinders in alignment, because if the parts are properly fitted the support 11, after being placed and secured in position around the head B of the lower cylinder, will properly center the upper cylinder, A, when it and its head are placed upon the support.

It is obvious that the support F might be otherwise constructed, in order to permit of the removal of a part or parts of it to afford ready access to the cylinder-heads and piston.

From Figs. 1. and 2 it will be seen that the internal shape of the support F is such that the head B of the lower cylinder can be raised to the point without coming to a bearing against the support,and without removing any part of the support. Access may thus be had to the follower and packing of the lower piston, D.

That I claim as my invention, and desire to secure by Letters, is

1. The combination, with upper and lower cylinders, of a sectional support for the upper cylinder, composed of parts one or more of which may be removed to afford access to the cylinder-heads and pistons, substantially as herein described.

2. The combination, with the upper and lower cylinders, of a circular support for the upper cylinder, divided vertically or composed of parts one or more of which may be removed to afford access to the cylinder-heads and pis tons, substantially as herein described.

3. The combination, with the upper and lower cylinders and heads, of a circular support for the upper cylinder, fitting outside of and centered by the heads and divided vertically or composed of parts one or more of which may be removed to afford access to the cylinder-heads and pistons, substantially as herein described.

4. The combination, with upper and lower cylinders, of a circular support for the upper cylinder, divided vertically and composed of upper and lower rings or circular flanges and struts or standards extending between them, substantially as herein described.

5. The combination, with upper and lower cylinders and their adjacent heads, of a circular sectional support for the upper cylinder, divided vertically and composed of upper and lower rings or circular flanges bored to fit around the heads and struts or standards extending between the rings or flanges, substantiall y as herein described.
